To whom a may camera:

Be it known that we, WVABREN MAcPrinnson and ERNEST VJ. Duncan, citizensof the United States, residing, respectively, at (Jambridge, MiddlesexCounty, State of Massachusetts, and Hudson, in said county and State,have invented a new and useful improvement in @vershoes and Processes ofManufacturing the Same, ofwhich the following is a specification, likereference characters on the drawings indicating like parts.

in the several figures.

This invention relates to overshoes of the arctic type. Such overshoesinclude a rubber bottom and a cloth top with fastenings, usuallybuckles, for securingthe opposite edges of the upper around the ankle ofthe wearer. The cloth upper usually includes an outer fabric and alining united thereto by an intermediate coating of rubber, and thebuckles are secured to straps which are anchored between the lining andthe outer fabric, both ends of each strap being secured between thesefabric pieces so that the straps form loops which project beyond theedge of the upper. Due to the presence of these loops, it has alwaysbeen considered impractical to bind the edges of the upper, andconsequently they have been left raw or unbound both at the top and alsoat the front of the shoe. While the rubber coating does reduce thetendency of the fabric to fray, it does not prevent it, especially withwoven fabrics. it is the chief object of the present invention,therefore, to improve the construction of overshoes of the type mentioned with a view to efi'ectually preventing the fraying of the exposededges of the upper. The invention also aims to devise "a process ofmanufacturing overshoes which will attain the end just mentioned withoutadding materially to the expense of manufacture of the shoe.

The nature. of the invention will be readily understood from thefollowing description when read in connection with the accompanyingdrawings, and the novel features will be particularly pointed out in theappended claims.

Referring now to the drawings,

Fig. l is a cross sectional view on a large scale through the edgebinding of the upper; and

Fig. 5 is a front elevation of parts or the upper immediately adjacentto the bound edge, these parts being shown somewhat magnified.

The shoe shown comprises a rubber bottom 2 and a cloth top 3, this shoebeing substantially like the present construction except for thefeatures of difierence hereinafter pointed out. In the particular shoeshown the top or upper includes two sidepieces 4 and 5, Fig. 2, whichare united at the back of the shoe by a seam'ti. The parts 4 and 5 formthe outer fabric of the upper, and they are secured to inner liningpieces 7, 8 and 9 by means of an intermediate coating of rubber. Theside pieces 4; and 5 are also adhesively united to a fabric piece 10which forms part of the bellows tongue, this piece usually beingintegral with the vamp of the shoe. A portion of the member 10 is alsosecured to the lining pieces 7 and 8. The construction so far describedis not materially difi'erent from that of the ordinary overslioe.

According to the present process the front and top edges of the outer orside pieces 4 and 5' are bound, preferably by overseamas indicated at12. This overseaming out and before they are secured to the lining, andthis operation can be performed very rapidly with the aid of asuitablesewing machine such, for example, as that known commercially as theMorrow binder. When the binding operation has been completed, the liningpieces 7, 8 and 9 are secured to the side pieces, the upper edges of thelining pieces being located slightly inside or below time bound edges ofthe parts 4 and 5, as clearly shown in Fig. 1. The edges 0;? the liningpieces may over lap the binding stitches slightly, but preterably theycome just to the stitches.

The clasps and cooperating eye pieces of the buckles preferably aresecured to the opposite edges of the upper by rubber straps or stays14-, each strap being doubled upon itself, as clearly shown in Fig. 3,to form a loop. Four of these straps are adhesively anchored between thetwo plies 4 and 10, at one edge of the upper, and four more between theplies 5 and at the opposite side of the shoe. Both the inner and outerfabrics 4.- and 10 have their inner surfaces coated with rubber, and insecuring them together the straps or stays let are located properly onthe inner surface of the part 4:, and the piece 10 is then placed on thepart -land the two parts are pressed together to cause their tackysurfaces to adhere, the edge of the inner fabric preferably beinglocated just within the bound edge of the outer fabric a, as clearly.shown in the drawings. This operation secures the stays or loops 14firmly between the inner and outer plies of the upper. The same processis fol lowed in anchoring the straps between the parts 5 and 10 at theopposite side of the shoe and in securing these parts together.

The remaining manufacturing operations may be carried'out in anysuitable-manner. These operations usually include the assembling of theparts of the shoe in the proper relationship to each other on a last,the varnishing of the rubber bottom, and the vulcanizing of the shoe Thecompleted shoe is shown in Fig. 1, and it will be observed that itpresents a much neater appearance than shoes of this type made in theusual manner. The ex- .posed edges of the parts 4 and 5 of the upper areeffectually prevented from fraye ing by the binding" stitches 12, andthe location of the edges of the parts 7 8, 9 and 10 just within thebound edges, enables this binding also to protect the edges of thelatter pieces. As above stated, the binding operation can be performedvery rapidly so that the present process involves an'increase in theexpense of manufacture -of the shoe which is negligible when comparedwith the advantage produced. This arrangement materially improves theshoe since it gives the shoe the appearance of having a bound edge bothinside and outside. Furthermore, it has the very important advantage ofpermitting the manufacture of the cloth top rom a woven fabric.Heretofore it has the universal practice to make the cloth "top ofknitted fabric, but this invention ens to use a we" fabric successfullyntialiy the manu- H I ce. At-

same time, the invention is 0 material shoe having a knitted fabric top.

value in a Having thus described our invention,'what we desire to claimas new is:

1. An overshoe of the arctic type comprising a rubber bottom and a clothupper, said 'upper including outer and inner plies of fabric securedtogether, fastening means secured between said plies at one of thefront,

edges of said upper to facilitate the fastening of the shoe about theankle of the wear- 'er. and a binder protecting the edge of one of saidplies, the edge of the other ply being located slightly inside of thebound edge of the first ply.

2. An overshoe of the arctic type comprising a rubber bottom and a clothupper, said upper including outer and inner plies of fabric, the edge ofsaid outer ply being ed to form a bellows top, said upper ineludingquarters and a bellows tongue, the edges of said quarters which extendup the front of the. shoe being overseamed and the opposite edges ofsaid bellows tongue being overlapped upon and united by means other thanthe overseam to the overseamed marginsof said quarters. and co operatingfastening devices secured between the edge portions of said tongue andquarters to facilitate the fastening of the shoe aboutthe ankle of thewearer.

4, That improvement in the prmess of manufacturing arctic overshoeshaving cooperating fastening for securing'the opposite edges of theupper together along the front of the ankle, which consists in cuttingthe parts of the upper out of suitable fabric, overseaming the edges ofthe quarters, securing fabric pieces to the inner surfaces of saidquarters with the edges of said inner pieces located slightly insidesaid overseamed edges, inserting fastener supporting straps between theedge portions said quarters and inner pieces before the are I united toanchor said straps securely between said parts, and then completing themanufacture of the overshoe in any sm'tahie are
